Background and aims: In order to contribute to the knowledge and conservation of the arid Andes flora, we explored how vehicular roads and elevation affect the composition and richness of plant communities. In addition, we aim to estimate the degree of plant invasion in the native community and identify the most common non-natives at three protected areas in Mendoza.
M&M: We recorded the composition and abundance of native and non-natives along the elevation gradient (from 1700 to 3900 m a.s.l.) in three vehicular roads (Villavicencio, Cordón del Plata, and Manzano-Portillo). At each road, 20 “T-plots” were located according to the MIREN protocol <www.mountaininvasions.org>.
Results: We identified 357 species, 42 were non-native (12%). Non-native cover was higher at Cordón del Plata (23%) than in the other protected areas (Manzano 11%, Villavicencio 6%). Most non-natives were herbaceous, except Rosa rubiginosa. Of all species, 64% of natives and 45% of non-natives were exclusive to a protected area, therefore native and non-native species composition was different among the protected areas. Non-native richness was higher near the road and decreased quadratically with elevation, but to explain native richness patterns it was necessary to consider the interaction between elevation and distance from the road. Native richness near the road was constant along the elevation gradient (~15 species) but showed a decreasing linear relationship away from the road.
Conclusions: Roads can modify the distribution patterns of species along the elevation in the Andes. |

Introducción y objetivos: Para contribuir al conocimiento y conservación de la flora de los Andes áridos exploramos cómo los caminos vehiculares y la elevación modulan la composición y riqueza en las comunidades vegetales. Además, buscamos estimar el grado de invasión de la comunidad e identificar a las especies exóticas más comunes en tres áreas protegidas de Mendoza. M&M: Registramos la composición y abundancia de plantas nativas y exóticas en el gradiente de elevación (desde 1700 m hasta 3900 m s.n.m) de tres caminos vehiculares (Villavicencio, Cordón del Plata, y Manzano-Portillo). En cada camino se localizaron 20 transectas tipo “T” de acuerdo al protocolo MIREN (www.mountaininvasions.org). Resultados: Identificamos 357 especies, 42 fueron exóticas (12%). La cobertura de exóticas fue mayor en Cordón del Plata (23%) que en las otras áreas protegidas (Manzano 11%, Villavicencio 6%). La mayoría de las plantas exóticas son herbáceas, excepto Rosa rubiginosa. El 64% de las especies nativas y el 45% de exóticas fueron exclusivas de un área protegida, y la composición de nativas y de exóticas fue diferente entre las áreas protegidas. La riqueza de exóticas fue mayor en cercanía al camino y decreció cuadráticamente con la elevación, pero para explicar la riqueza de nativas es necesario considerar la interacción entre elevación y distancia al camino. La riqueza de nativas cerca del camino fue constante en el gradiente de elevación (~15 especies) pero mostró una relación lineal decreciente lejos del camino. Conclusiones: Los caminos alteran los patrones de distribución de las especies a lo largo de la elevación en los Andes.
